Using photographs taken of the hull during an underwater hull inspection or samples of a ship's hull collected during an underwater hull cleaning, I determine when and where marine hull growth formed. This can clarify whether the owner of the vessel improperly handed over the vessel or whether the charterer neglected their obligations to keep the hull clean. This can provide decisive evidence in a legal disputes. This type of report is still relatively unknown, and I am pioneering the field successfully.

In my academic career, I focus on understanding how we humans have caused evolution of aquatic invertebrates, such as oysters, crabs and barnacles, applying barcoding, whole genome sequencing, population genetics, phylogenomics and museomics. I often collaborate to broaden my methodological toolkit. Museum collections, however, represent the core of my work, as they allow us to "travel back in time" and ask actual Zeitzeugen, the collections, how the world used to be.
